DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1A, a ventilating roof in accordance with theinvention comprises a roof structure 10 including a ventilating ridgeroll 110 having a triangular longitudinal section, the ventilating ridgeroll 110 having two vent holes 111 at two ends respectively, two basemembers 120 having a bent inner end, and a gap 100 formed between thebase members 120; and two side panels 20 including a main panel 200secured to the vent hole 111 and a drain hole 210 at a lower end, thedrain hole 210 secured to an intermediate portion of the base member120.

It is envisaged by the invention that an angle ∠ between the bent innerend of the side panel 120 and the main portion of the side panel 120 isbetween 120 and 180 degrees. Width of the ventilating ridge roll 110 isless that that of the roof structure 10. The vent hole 111 has anopening larger than an opening of the drain hole 210. Ventilation of ahousing having a ventilating roof of the invention can be carried out byexiting hot air out of the housing via both a first path from the gap100 and one vent hole 111 and a second path from the gap 100 and theother vent hole 111. The ventilation is carried out by naturalconvection without consuming power. The side panels 20 can prevent rainwater from falling into the roof. Rain water may fall into the roof viathe vent holes 110 and advantageously flow out of the roof via the drainholes 210 to completely drain. Thus, the invention is also capable ofpreventing rain water from entering a house.

Referring to FIG. 1B, another configuration of the first preferredembodiment of the invention is characterized by the ventilating ridgeroll 110 is convex and the inner end of the base member 120 is not bent.

Referring to FIG. 2, a ventilating roof in accordance with a secondpreferred embodiment of the invention is shown and comprises two basemembers 30 including an inner end member 320, a gap 300 formed betweenthe base members 30, two inclined side panels 310 mounted on the basemembers 30, a bent top support 311 at a joining portion of tops of theside panels 310, each side panel 310 having a vent hole 440 at a bottomend; and a ventilating ridge roll 40 having a triangular longitudinalsection and including two inclined main panels 400 joined at a top, eachmain panel 400 having a vent hole 410 at a top end and a drain hole 420at a bottom end, and an elongated cover 430 mounted on a top of theventilating ridge roll 40.

It is envisaged by the invention that width of the side panels 310 isless that that of the base members 30. The vent hole 410 has an openinglarger than an opening of the drain hole 420. Ventilation of a housinghaving a ventilating roof of the invention can be carried out by exitinghot air out of the housing via both a first path from the gap 300 andone vent hole 410, a second path from the gap 300 and the other venthole 410, a third path from the gap 300, one vent hole 440, and one venthole 410, and a fourth path from the gap 300, the other vent hole 440,and the other vent hole 410. The ventilation is carried out by naturalconvection without consuming power. The ventilating ridge roll 40 canprevent rain water from falling into the roof. Rain water may fall intothe roof via the vent holes 410, flow down on the side panels 310 andadvantageously flow out of the roof via the drain holes 420 tocompletely drain. Thus, the invention is also capable of preventing rainwater from entering a house.

Referring to FIGS. 3, 4A and 4B, a ventilating roof in accordance with athird preferred embodiment of the invention is shown and comprises twobase members 50 including a gap 500 formed between the base members 50;two sets of two engaged ventilation pipes 70 having a plurality of ventholes 700, each set of the ventilation pipes 70 mounted on an inner endof the base member 50, a ventilating ridge roll 60 mounted on the setsof the ventilation pipes 70, and two exits 80 each formed between an endof the ventilating ridge roll 60 and one base member 50 by theventilation pipes 70.

It is envisaged by the invention that width of the ventilating ridgeroll 60 is greater than that of the gap 500. Ventilation of a housinghaving a ventilating roof of the invention can be carried out by exitinghot air out of the housing via both a first path from the gap 500 andone exit 80 via the vent holes 700 of one set of the ventilation pipes70 and a second path from the gap 500 and the other exit 80 via the ventholes 700 of the other set of the ventilation pipes 70. The ventilationis carried out by natural convection without consuming power. Theventilation pipes 70 can prevent rain water from falling into the roof.Thus, the invention is also capable of preventing rain water fromentering a house.

Referring to FIG. 5, a ventilating roof in accordance with a fourthpreferred embodiment of the invention is shown and comprises aventilating ridge roll 60 having one end formed with a portion of thebase member 50, a gap 500 through the base member 50, three engagedventilation pipes 70 mounted on the base member 50, and an exit 80formed between an end of the ventilating ridge roll 60 and the basemember 50 by the ventilation pipes 70.
